The Battle of Lützen (6th November 1632) was one of the most decisive battles of the Thirty Years' War. It was a Protestant victory, but cost the life of one of the most important leaders of the Protestant alliance, the Swedish King Gustav II Adolf, which caused the Protestant campaign to lose direction.

Two days before the battle, on 14 November (in the Gregorian calendar, 4th in the Julian calendar) the Roman Catholic general Wallenstein decided to split his men and withdraw his main headquarters back towards Leipzig. He expected no further move that year from the Protestant army, led by the Swedish king Gustavus Adolphus, since unseasonably wintry weather was making it difficult to camp in the open countryside; however, Gustavus Adolphus' army marched out of camp towards Wallenstein's last-known position and attempted to catch him by surprise, but his trap was sprung prematurely on the afternoon of 15 November, by a small force left by Wallenstein at the Rippach stream, about 5–6 kilometres south of Lützen. A skirmish delayed the Swedish advance by two or three hours, thus when night fell the two armies were still separated by about 2–3 kilometres (1–2 miles).

Wallenstein had learned of the Swedish approach on the afternoon of 15 November. Seeing the danger, he dispatched a note to General Pappenheim ordering him to return as quickly as possible with his army corps. Pappenheim received the note after midnight, and immediately set off to rejoin Wallenstein with most of his troops. During the night, Wallenstein deployed his army in a defensive position along the main Lützen-Leipzig road, which he reinforced with trenches. He anchored his right flank on a low hill, on which he placed his main artillery battery.

Morning mist delayed the Swedish army's advance, but by 9 am the rival armies were in sight of each other. Because of a complex network of waterways and further misty weather, it took until 11 am before the Protestant force was deployed and ready to launch its attack. Gustavus Adolphus rode his war-horse Streiff, a brown Oldenburg that he had purchased from a Colonel Johan Streiff von Lauenstein for the sum of 1000 riksdaler (the sum for a regular horse was about 70-80 riksdaler). Its saddle of gold embroided red velvet was a gift from the King's wife, Maria Eleonora. Protecting the upper part of the King's body was a buff coat made of elkhide - his old musket wound to his shoulder blade making it impossible for him to wear heavy armour.[2]

Initially, the battle went well for the Protestants, who managed to outflank Wallenstein's weak left wing. After a while, Pappenheim arrived with 2,000–3,000 cavalry and halted the Swedish assault. This made Wallenstein exclaim, "Thus I know my Pappenheim!". However, during the charge, Pappenheim was fatally wounded by a small-calibre Swedish cannonball. At the same time, Pappenheim's counterattack collapsed. He died later in the day while being evacuated from the field in a coach.

The cavalry action on the open Imperial left wing continued, with both sides deploying reserves in an attempt to gain the upper hand. Soon afterwards, towards 1:00 pm, Gustavus Adolphus was himself killed while leading a cavalry charge on this wing. In the thick mix of gun smoke and fog covering the field, he was separated from his fellow riders and killed by several shots.[3] A bullet crushed his left arm below the elbow. Almost simultaneously his horse suffered a shot to the neck that made it hard to control. In the mix of fog and smoke from the burning town of Lützen the king rode astray behind enemy lines. There he sustained yet another shot in the back, was stabbed and fell from his horse. Lying on the ground, he received a final, fatal shot to the temple.[2] His fate remained unknown for some time. However, when the gunnery paused and the smoke cleared, his horse was spotted between the two lines, Gustavus himself not on it and nowhere to be seen. His disappearance stopped the initiative of the hitherto successful Swedish right wing, while a search was conducted. His partly stripped body[3] was found an hour or two later, and was secretly evacuated from the field in a Swedish artillery wagon.

Meanwhile, the veteran infantry of the Swedish center had continued to follow orders and tried to assault the strongly entrenched Imperial center and right wing. Their attack was a catastrophic failure—they were first decimated by Imperial artillery and infantry fire and then ridden over by Imperial cavalry charging from behind the cover of their own infantry. Two of the oldest and most experienced infantry units of the Swedish army, the 'Old Blue' Regiment and the Yellow or 'Court' Regiment were effectively wiped out in these assaults; remnants from them streamed to the rear. Soon most of the Swedish front line was in chaotic retreat. The royal preacher, Jakob Fabricius, rallied a few Swedish officers around him and started to sing a psalm. This act had many of the soldiers halt in hundreds. The foresight of Swedish third-in-command 'Generalmajor' Dodo zu Innhausen und Knyphausen also helped staunch the rout: he had kept the Swedish second or reserve line well out of range of Imperial gunfire, and this allowed the broken Swedish front line to rally.

By about 3 PM, the Protestant second-in-command Bernhard of Saxe-Weimar, having learned of the king's death, returned from the left wing and assumed command over the entire army. He vowed to win the battle in retribution for Gustavus or die trying, but contrary to popular legend tried to keep the king's fate secret from the army as a whole. (Although rumours were circulating much earlier, it was only the following day that Bernhard collected his surviving officers together and told them the truth.)

The result was a grim struggle, with terrible casualties on both sides. Finally, with dusk falling, the Swedes captured the linchpin of Wallenstein's position, the main Imperial artillery battery. The Imperial forces retired back out of its range, leaving the field to the Swedes. At about 6 pm, Pappenheim's infantry, about 3,000–4,000 strong, after marching all day towards the gunfire, arrived on the battlefield. Although night had fallen, they wished to counterattack the Swedes. Wallenstein, however, believed the situation hopeless and instead ordered his army to withdraw to Leipzig under cover of the fresh infantry.

The body of Gustav II Adolf was plundered of its clothes and gold jewellery and left on the battlefiled dresses only in his shirts and long stockings. His buff coat was taken as a trophy to the emperor in Vienna. It was returned to Sweden in 1920, in recognition of relief efforts by the Swedish red cross during and after the First World War. The king's horse, Streiff, followed the procession with the king's body through northern Germany. When Streiff died at Wolgast in 1633, his hide was saved and sent to Stockholm and Sweden where it was mounted on a wooden model. "The Hero-king's war horse" would soon be displayed in the Royal Armoury as a monument to the King. Today Streiff is permanently displayed in the Royal Armoury in Stockholm, Sweden.[2]

After the fateful Battle of Lützen the dead Gustavus Adolphus was first taken to Meuchen to be cleaned and then to Weissenfels for embalming. The embalmed body was dressed in a beautiful gold and silver woven dress and brought in solemn procession to the port town Wolgast. The corpse was kept there for several months. Not until the summer 1633 it was time for the departure to Sweden. The dead king was then brought in a procession down to the sea side. It consisted of people from Sweden and the nearby areas. Banners from all counties and principalities, the blood banner and the head banner were carried. The armor (kyrisset), the sword and the horse (livhästen) functioned as symbols for the dead king. The widow, Maria Eleonora, rode in a coach, but Gustavus Adolphus young daughter Christina did not participate. The procession ended by the water, where the ship Stora Nyckeln was to bring the dead across the sea to the Swedish town Nyköping.

When the ship arrived to Nyköping, there were rumoures of dreadful portents. A shoe makers wife was said to have given birth to a freak and a calf with two heads had been born. The royal corpse was kept in Nyköping until the funeral in summer 1634. When it was time for the final journey to Stockholm, a ceremony was held at Nyköping Castle where the king's old teacher Johan Skytte held a speech and the bishop Johannes Rudbeckius read a sermon dedicated to the king’s daughter Christina.

In the procession to Stockholm there were eight war trophies from Lützen and several trophy banners from Leipzig, marking Sweden's status as a superpower. Five black-dressed members of the privy council (riksämbetsmän) carried the regalia before the royal corpse, which lied on a bier adorned with black cloth. Right behind the bier came the king's brother in law, the Count Palatine Johan Casimir with his sons Karl Gustav and Adolf Johan. This time both the grieving Dowager Queen, Maria Eleonora and the king’s seven-year-old daughter Christina attended. The sorrowful procession moved slowly across the country towards the capital.

The streets of Stockholm were arranged for the funeral. The burghers had been told to white lime the houses along the procession route and trophies from Lützen and Leipzig had been placed out. On the funeral day, June 22, the participants gathered outside town. The dead king was taken off his coach and carried into the capital to the Church. Bishops and priests welcomed the procession in the outskirts of the town and along the road from the gate to the church money were thrown to the people. When the procession reached the Riddarholms church the blood banner was placed over the entrance to the tomb and the bier with Gustavus Adolphus was placed in the middle of the choir. A grand ceremony was held by the Bishop Johannes Botvidi, with a sermon dedicated to the Dowager Queen Maria Eleonora. When the ceremony was over the dead king was placed in the tomb. The end of the ceremony was promulgated by cannons fireing over the town for two hours.[4][5]

Strategically and tactically speaking, the Battle of Lützen was a Protestant victory. Having been forced to assault an entrenched position, Sweden lost about 6,000 men including badly wounded and deserters, many of whom may have drifted back to the ranks in the following weeks. The Imperial army probably lost slightly fewer men than the Swedes on the field, but because of the loss of the battlefield and general theatre of operations to the Swedes, fewer of the wounded and stragglers were able to rejoin the ranks.

The Swedish army achieved the main goals of its campaign. The Imperial onslaught on Saxony was halted, Wallenstein chose to withdraw from Saxony into Bohemia for the winter, and Saxony continued in its alliance with the Swedes.[6] A more long-lasting consequence of the battle was the death of the Swedish king Gustavus Adolphus, leader of the Protestant forces. Without him to unify the German Protestants, their war effort lost direction. As a result the Catholic Habsburgs were able to restore their balance and subsequently regain some of the losses Gustavus Adolphus had inflicted on them.

Crucially, Gustavus Adolphus's death enabled the French to gain much firmer control of the anti-Habsburg alliance. Sweden's new regency was forced to accept a far less dominant role than it had held before the battle. The war was eventually concluded at the Peace of Westphalia in 1648.

Near the spot where Gustavus Adolphus fell, a granite boulder was placed in position on the day after the battle. A canopy of cast iron was erected over this “Swedes' stone” (German: Schwedenstein) in 1832, and close by, a chapel, built by Oskar Ekman, a citizen of Gothenburg (d. 1907), was dedicated on 6 November 1907.[7][8] The fallen king is remembered every year in Sweden, on Gustavus Adolphus Day the 6 November, with serene celebrations and special pastries.

At this time, the Catholic Holy Roman Empire used the Gregorian calendar, but Protestant Sweden still used the Julian calendar. Hence the Battle of Lützen occurred on 16 November for the Catholics but on 6 November for the Swedes. In Sweden, the death of Gustavus Adolphus has a long tradition of being commemorated on 6 November, Gustavus Adolphus Day, despite the country's adoption of the Gregorian calendar in the 18th century.
